5 steps
- Rate = 8% a year, so 0.666667% is accrued each month on the qualifying balance.
- Deposits land on or before the 5th, so each one earns interest from the month it is made (scheme paragraph 10).
- Interest accrued through the year is credited in one lump at the end of the financial year, and only then compounds.
- Total deposited over 15 years = 2250000; interest = 2148642.46.
- Balance after 15 years = 4398642.46.

What the public provident fund calculator calculates
Projects the maturity value of an Indian Public Provident Fund account using the scheme's own interest rule - monthly accrual on the lowest balance after the 5th, credited once a year - with a full year-by-year schedule.
How to use this public provident fund calculator
Enter Deposit each year, Deposit each month, Notified annual interest rate and Years held. Balance at maturity updates as you type. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Balance at maturity, Total deposited and Total interest earned.
The method follows Public Provident Fund Scheme, 2019 (G.S.R. 913(E)), Government of India - paragraph 4 deposit limits, paragraph 9 maturity after fifteen years, paragraph 10 interest on the lowest balance between the close of the 5th day and the end of the month, credited at the end of each financial year and Ministry of Finance, Department of Economic Affairs (Budget Division) - quarterly notification of small savings interest rates, the source of the rate this engine takes as an input.
What you can compare
Change one input at a time to see how it affects Balance at maturity, Total deposited and Total interest earned. The inputs you can vary are Deposit each year, Deposit each month, Notified annual interest rate, Years held and Balance already in the account.
Understanding Balance at maturity, Total deposited and Total interest earned
An illustration of the scheme arithmetic at the rate you enter. The PPF rate is re-notified every quarter, so a real account will not compound at one fixed rate. It is not tax, investment or eligibility advice.
Results are general information, not financial, tax, legal, medical or engineering advice. Check any decision that matters with a qualified professional.
